Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186160, here are decompositions:

3 + 186157 = 186160
11 + 186149 = 186160
41 + 186119 = 186160
47 + 186113 = 186160
53 + 186107 = 186160
89 + 186071 = 186160
137 + 186023 = 186160
167 + 185993 = 186160

Showing the first eight; more decompositions exist.
